Decoding GM 4bbl intakes
Permalink  

 I have two GM intake manifolds and I'm not sure of their vintage. First one part #3919803 . Has a large letter "R" on runner right behind "T stat" housing.

Second one part #346240  also stamped GM   K6. Has breather /filler tube at front of intake so I am assuming this is the older of the two.

Would like to know what year/ models these are for . Right now they are living rent free in my garage. If they are fairly common I will  probably toss them for scrap.

I'm thinking your 346240 is missing a digit if it has an oil fill tube hole. I'm just not sure what digit is missing but I think it will be a 7 digit casting number.

That wouldn't have a hole for an oil fill tube would it?

 Could you post pictures? That may help.

leeroy, if you'll box and ship it to ontario, i'll take the 803 intake, let me know what you want for it.

common '68 Qjet intake used for 327s and 350s that model year.

#346240 casting is a series from the mid to late 70's. Is this possibly an Olds 307 or 403 intake from that era? These had oil fill tube at front just like an early Chevrolet.
